NOVEL CHALCONE DERIVATIVES WITH CYTOTOXIC ACTIVITY

摘要

Chalcone derivatives of the general formula (I), wherein two from among A, B and Z which are adjacent to each other are linked and form a moiety selected from -O-(CH2)n-S(O)m-, -S(O)m-(CH2)n-O- and -O-(CH2)n-O-, and the remaining one from among A, B and Z is H; or two from among A, B and Z, independently from each other, are selected from a group consisting of OH, -O-C1-C6-alkyl and -S(O)m-C1-C6-alkyl, and the remaining one from among A, B and Z is H; R is H, C1-C6-alkyl, carboxy-C1-C6-alkyl, -(CH2)P- NR1R2 or O(CH2)3NH(CO)CF3, where R1 and R2 both independently are C1-C6-alkyl; or R1 and R2 are linked together to form polymethylene group -(CH2)q-, and with N atom, to which they are attached, form a 5- or 6-membered ring, in which one of carbon atoms may be optionally replaced with O, N, or S; Y is -CH=CH-, -O-, -S- or -CH=N-; X1, X2, X3 independently are H, halogen atom, OH, -C1-C6-alkoxy, carboxy-C1-C6-alkoxyl, di(C1-C6- alkyl)amino-C1-C6-alkoxy, -0-PO(OH)2, NO2 or NH2; m = O, 1 or 2; n = 1 or 2; p = 2 to 6; q = 4 or 5; and acid addition salts, salts with bases and C1-C6-alkyl esters thereof. The compounds may be useful as cytotoxic drugs for the treatment of neoplastic diseases. Formula (I).
